- Abstract:
-
Analysis of soil physical property and soil retention, water-holding rate of litter, water infiltration of Ziquejie terrace to research water conservation function, in order to sustainable development of the terrace. The results showed that: (1)Each layer of soil bulk density and porosity, soil retention, water infiltration rate exceeded hillsides, and notable differences. (2)Water conservation index and physical property index have some relationships. Soil retention and soil bulk density and porosity, properties have close relationships. Soil structure, forest litter is decomposed of environment and condition affected by soil bulk density and porosity, and last affect water content. Soil bulk density and porosity affect soil infiltration rate. Soil porosity, soil structures have good quality, and then have high rate of infiltration.
